New Rush featurette goes behind the scenes of Lauda and Hunt rivalry

The story of Niki Lauda and James Hunt's infamous 1976 world championship rivalry is so packed with twists and turns, we're surprised it has taken this long for a feature-length motion picture to come along.

But A Beautiful Mind director Ron Howard has grabbed the tale by the scruff of its neck - pitched Chris Hemsworth as the charismatic James Hunt and Daniel Brühl as the brooding Niki Lauda – and thrown a typically Hollywood budget at it to ensure the intense competitive spirit is captured on film.
